“Try on some of them” or “Try some of them on”?

I’ve learnt that some phrasal verbs such as “pick up” or “try on” require us to put the object, especially when it is a pronoun, between the verb and preposition. Is it also possible to say “You should try some of them on before buying”? Or is it better to say “You should try on some of them”?

I’m looking forward to hearing from you. Thank you in advance.
